libxfconf/XfconfChannel is not for backend developers.  I'm not 
designing the client library to cater to a (hopefully) very small set of 
users.  Backend developers can use dbus-send or the dbus-glib bindings 
directly (see xfconf/trunk/xfconf/xfconf-dbus-bindings.h) for their 
debugging work.  If they can only reproduce their problem with libxfconf 
in the mix, a debug build of the library could be set up to printf() any 
errors it receives from the daemon.
